Trike Class in Nevada

[garb55]

Trimobiles

The 2015 Nevada Legislature changed the definition of “trimobile” to include three-wheeled vehicles that are powered by one or two wheels. (A motorcycle with a sidecar, however, remains a motorcycle.) This change went into effect May 14, 2015.
A Class C or higher driver's license is required to drive a trimobile.
A Class M driver's license is not required. Helmets are not required. Glasses, goggles or a face shield are required unless the trimobile is equipped with a face shield that meets federal standards. (NRS 486.231)

There has not been enough interest for MSF to offer a 3 wheel class in Nevada and now that the law no longer requires an M endorsement to ride one it would be doubtful that they will ever offer one in the state.
